A base end of a hose body 31 as a communication tube including a flexible elongated cylindrical hose body 30 is detachably and airtightly connected. The hose body 30 is airtightly connected to the suction side of the electric blower 5. Further, at the tip of the hose body 30, there is provided a hand operation part 32 for bending the floor brush 52, which is bent in a substantially V shape. Then, on the upper side of the intermediate portion in the axial direction of the hand operation portion 32, a substantially cylindrical grip portion 33 that is branched and protrudes toward the base end side of the hand operation portion 32 is integrally provided. . This grip 33
Is gripped by the user when operating the hose body 31.

A plurality of various setting buttons (not shown) for setting the operation mode of the electric blower 5 and the like are arranged side by side in a row on the upper side surface of the hand operation section 32 on the tip side of the grip section 33. Has been done. Further, on the lower end side of the hand operation unit 32 facing the plurality of setting buttons, the suction air sucked by the electric blower 5 is swirled,

The hand dust cup 41 is attached to the suction side of the dust cup 21 in the cleaner body 1, that is, the floor brush 52 side.

Further, the hand dust cup 41 is dust that should not be sucked into the dust cup 21 in the cleaner body 1, for example, a relatively large foreign substance such as currency or insects,
Foreign matters such as water that may cause a failure of the electric blower 5 are efficiently separated by centrifugal separation due to their own weight. Further, the wind velocity flowing into the hand dust cup 41 is lower than the wind velocity flowing into the dust cup 21, so that the dust separation performance of the hand dust cup 41 is
It is set lower than the dust separation performance of 21.

The hand dust cup 41 is provided with a substantially bottomed cylindrical hand cup portion 43 as a cyclone dust collecting portion having an opening 42 at the upper end which is one end in the axial direction and provided with an outlet 42. There is. The hand permitting cup portion 43 is formed in a bottomed elongated cylindrical shape, and is attached to the hand permitting operation portion 32 in a state where the axial direction is along the axial direction of the hand permitting operation portion 32 of the hose body 31. Here, the inner diameter of the hand cup portion 43 is the cup portion of the dust cup 21 in the cleaner body 1.
It is smaller than the inner diameter of 23. Also, this hand cup part 43
The height dimension inside is smaller than the height dimension inside the cup portion 23 of the dust cup 21. Therefore, the volume inside the hand cup portion 43 is smaller than the volume inside the cup portion 23 of the dust cup 21.

Further, the outlet 42 of the hand cup portion 43 is
Suction opening communicating with the suction side of the hose body 31 of the hand operation part 32
It is detachably connected to the 35 in an airtight manner. In addition, a substantially circular inflow port 44 that is airtightly communicated with an exhaust opening 36 that is opened at the lower end surface of the hand operation unit 32 is opened on the upper outer surface on the outlet 42 side of the hand operation cup unit 43. There is.

Further, inside the hand cup portion 43,
The suction wind sucked from the inlet 44 is passed through this hand cup part 43.
An approximately cylindrical hand-held cyclone unit 45 having a function of a wind direction control unit for turning inside is formed. A swirling air exhaust port 46 is provided at the center of the hand cyclone unit 45 to swirl the suction air sucked into the hand cup unit 43 and then exhaust the swirling air.

Here, in addition to the above-mentioned inflowing wind speed, the dust separation performance of the hand dust cup 41 includes the opening angle of the inlet 44, the opening position of the inlet 44, and the fit of the hand cyclone portion 45 to the hand cup portion 43. It is determined by the insertion amount.

Further, on the opening end face of the swirling air exhaust port 46 of the handy cyclone unit 45, dust which could not be separated by centrifugal separation by the whirling air in the handy hand cup unit 43 is captured, and inside the handy hand cup unit 43. A mesh-shaped hand filter body 47 for collecting dust is attached. This hand filter body 47
Is composed of a mesh body having a coarser mesh than the first filter body 28 in the cleaner body 1.

On the other hand, a floor brush 52, which serves as a suction port body, is detachably and airtightly connected to the distal end portion of the hand-operated operating portion 32 of the hose body 31 through an extension pipe 51, which serves as an expandable / contractible connection pipe. There is. Therefore, the floor brush 52 is airtightly connected to the suction side of the hose body 31. A nozzle body such as a crane mouth as a suction port body (not shown) is detachably and airtightly connected to the tip of the hand operation section 32 of the hose body 31.

Next, the operation of the above embodiment will be described.

In the state shown in FIG. 1, while gripping the grip portion 33 of the hand operation portion 32, a predetermined setting button of the hand operation portion 32 is turned on to drive the electric blower 5 in the cleaner body 1. .

Then, air is sucked from the tip of the floor brush 52 together with dust. Then, the dust-containing air becomes suction air, and is sucked into the hand operation section 32 of the hose body 31 through the extension pipe 51.

The suction air sucked into the hand operating portion 32 is sucked into the hand cup portion 43 from the inlet 44 of the hand dust cup 41 through the exhaust opening 36 of the hand operating portion 32. .

Thereafter, the suction air sucked into the hand cup portion 43 is swirled by the hand cyclone portion 45 in the hand cup portion 43 into a swirling wind, which is sucked together with the suction air. Foreign matter such as currency, insects, or water having a relatively large specific gravity among the collected dust falls into the inside of the hand cup portion 43 by centrifugal separation due to its own weight, and is collected in the hand cup portion 43.

Further, the sucked air swirled in the hand cup portion 43 passes through the hand filter body 47 attached to the swirl air exhaust port 46 of the hand cyclone portion 45. At this time, a relatively small foreign matter that could not be separated by centrifugation in the hand cup part 43 is captured by the hand filter body 47.
Dust is collected in 43.

The suction air that has passed through the hand filter body 47 and is sucked into the swirling air exhaust port 46 of the hand cyclone unit 45 is sucked into the hose body 31 from the intake opening 35 of the hand operating unit 32. After being cleaned, it is sucked from the suction pipe 14 to the suction cylinder portion 26 of the dust cup 21 through the suction port 13 of the cleaner body 1.

Then, from the intake cylinder portion 26 to the dust cup
The suction air sucked into the cup portion 23 of 21 is swirled by the cyclone portion 25 in the cup portion 23 to be swirled, and the relatively small dust sucked together with the swirling wind is caused by its own weight. By centrifugal separation, it falls into the inside of the cup portion 23, and dust is collected inside the cup portion 23.

Further, the suction wind swirled in the cup portion 23 passes through the first filter body 28 of the cyclone portion 25. At this time, fine dust that cannot be separated by centrifugation in the cup portion 23, that is, fine dust, is captured by the first filter body 28 and collected in the cup portion 23.

After that, the suctioned air that has passed through the first filter body 28 passes through the second filter body 29. At this time, finer fine dust that could not be captured by the first filter body 28 is captured by the second filter body 29.

The suction air that has passed through the second filter body 29 is sucked into the electric blower 5 to be exhaust air, and then exhausted to the outside from the exhaust port of the cleaner body 1.

As described above, according to the above-described embodiment, even if relatively large foreign matter such as currency or insects that should be taken out immediately after being sucked in is sucked from the floor brush 52, these foreign matters are cleaned. Before being sucked into the dust cup 21 inside the machine body 1, the hand operation part of the hose body 31
It can be separated by the hand dust cup 41 attached to 32. Therefore, use this hand dust cup 41 for the hand operation part.
By removing them from 32, these foreign matters can be taken out and treated easily and surely, so that the treatment of the foreign matters which should not be sucked into the dust cup 21 in the cleaner body 1 can be performed reliably and easily.

Further, by using the hand dust cup 41 as a cyclone dust collecting portion for separating dust by centrifugal separation, a pressure loss at the time of separation of these relatively large foreign matters by the hand dust cup 41, so-called power down, occurs. Since it does not easily occur, it is possible to prevent a decrease in the suction work rate by the electric blower 5.

At the same time, by using the handy dust cup 41 as the cyclone dust collecting portion, even if foreign matter such as water which may cause a failure of the electric blower 5 is sucked into the electric blower 5, even if the foreign matter is sucked into the electric blower 5. Since the foreign matters can be reliably separated by the hand dust cup 41 of the hand operating portion 32 without being sucked into the dust cup 21 in the cleaner body 1, the malfunction of the electric blower 5 in the cleaner body 1 can be further prevented. It can be surely prevented. Therefore, foreign matter such as water can be sucked and captured as long as the dust can be separated by the hand dust cup 41.

Also, the hand cup portion of the hand dust cup 41
43 is a bottomed slender cylindrical shape having a smaller volume than the dust cup 21 in the cleaner body 1, and the hand operating portion 32 of the hand operating portion 32 is aligned in the axial direction of the hand operating portion 32 of the hose body 31. Since it is attached to the lower side facing the grip portion 33, without lowering the operability of the hose body 31 by the hand operation portion 32,
Foreign matter sucked from the floor brush 52 or the gap nozzle can be reliably and easily treated by the hand dust cup 41, and the foreign matter separated by the hand dust cup 41 can be easily treated.

Further, by attaching the hand dust cup 41 to the hand operating portion 32 of the hose body 31, regardless of what is connected to the hand operating portion 32, that is, the extension pipe having the floor brush 52 attached to the tip thereof. Even if any of the 51, the floor brush 52, the clearance nozzle, etc. is attached to the tip of the manual operation section 32, the dust sucked from the floor brush 52, the clearance nozzle, etc. can be collected in a plurality of stages of the manual dust cup 41 and the dust cup 21. The dust can be separated and collected, and in the state where the grip portion 33 of the hand operation portion 32 is gripped, the hand operation portion 32
Since the hand dust cup 41 can be easily attached and detached,
The handy dust cup 41 can be easily handled.

Further, the dust separation performance of the hand dust cup 41 is set to be lower than the dust separation performance of the dust cup 21 in the cleaner body 1, so that the hand dust cup
The relatively large dust is separated and collected by 41, and the relatively small dust is separated and collected by the dust cup 21.

Therefore, it is possible to prevent unnecessary dust from accumulating in the hand dust cup 41, efficiently prevent the suction efficiency from being lowered by the hand dust cup 41 and the dust cup 21, and suck the air blown by the electric blower 5. Can reliably separate and collect dust of various sizes. Therefore, these hand dust cups 41 and dust cups
The dust collection efficiency of 21 can be improved more reliably.

Further, the hand filter body 47 of the hand dust cup 41 is made coarser than the first filter body 28 of the dust cup 21 in the cleaner body 1, and the exhaust filter side of the first filter body 28 is located on the exhaust side. Since the second filter body 29 has finer eyes than the first filter body 28, the coarseness of each of the hand filter body 47, the first filter body 28 and the second filter body 29 is in the suction air passage. It becomes fine along.

Therefore, these hand filter bodies 47, the first
The dust trapping efficiency of each of the filter body 28 and the second filter body 29 can be improved, and uneven clogging in each of the hand filter body 47, the first filter body 28, and the second filter body 29 can be prevented. It can be prevented reliably and easily with a simple structure.

Although the cyclone type canister type vacuum cleaner has been described in the above embodiment, a pot type or upright type vacuum cleaner can also be used in correspondence.

Further, the dust collecting portion in the cleaner body 1 is the dust cup 21 which is a cyclone dust collecting portion, but the dust collecting portion in the cleaner body 1 is a dust collecting chamber to which the paper pack is attached. You can also When a paper pack is attached to this dust collection chamber, the hand dust cup 41 attached to the hand operating portion 32 of the hose body 31 can reliably prevent foreign matter such as water and needles from entering the paper pack. Therefore, it is possible to surely and easily prevent deterioration and damage of the dust separation performance due to this paper pack.

[0048]

According to the present invention, the dust sucked from the suction port body is first sucked into the front separating portion for centrifugally separating the dust by rotating the suction air, so that the foreign matter is separated at this front separating portion. It is possible, and it is possible to easily treat the foreign matter sucked from the suction port body, and since the front separating portion has a smaller volume than the main body separating portion, the operability does not deteriorate.
